In foundation 6 block-grid, how can one make a grid of non equal height elements that is placed immediately after their parent.
Example (image)
So all the bottom grey blocks moves up to where the orange blocks are, instead of being on their own newline
<div class="row small-up-1 medium-up-6 large-up-4">
<div class="column column-block f1" style="height: 100px;">
<div>
<h1>block 1</h1>
<p></p>
</div>
</div>
<div class="column column-block f1" style="height: 250px;">
<div>
<h1>block 2</h1>
<p></p>
</div>
</div>
<div class="column column-block f1">
<div>
<h1>block 3</h1>
<p></p>
</div>
</div>
<div class="column column-block f1" style="height: 175px;">
<div>
<h1>block 4</h1>
<p></p>
</div>
</div>
<div class="column column-block f1">
<div>
<h1>block 5</h1>
<p></p>
</div>
</div>
<div class="column column-block f1">
<div>
<h1>block 6</h1>
<p></p>
</div>
</div>
<div class="column column-block f1">
<div>
<h1>block 7</h1>
<p></p>
</div>
</div>
</div>
If this is not possible in foundation, is their than anyone who can advice towards a technique that does allow this?
Thanks in advance to all.
